' nannies-CLIP.

'To all wl wmfit may concern Be 'it known that 1,. JAMES VVILLIAivi SMAL MAN, a subject of the King of Great- Britain and Ireland, ofBlackdown, near Leamington, in the county of Varwick,

England, have invented an Improved-Haulage-Clip, of which the following is a specification. I The accompanying drawings il'lustraten haulage clip constructed according to my invention.

Figure 1 proved clip. of the right-hand. shell. Fig. 3 is a similar view of the left-hand shell, Fig. 4 is a side elevation of the head and body of the lever. Fig. 5 is a corresponding plan. Fig. (3

includes the subsidiary stops.

This invention is a modification of the invention described in the specification to my United States Letters Patent No. 1,077,438, granted Nov. 4, 1913.

In the haulage clip shown by the drawingsto that specification, there is only one pair of stops. These stops extend laterally from the body of the lever.

In a haulage clip made in accordance with the present invention, the head of the lever has rounded shoulders and a wedge-like continuation with a reduced base; and there are two pairs of stop's-a principal and a sphsidiary pair. The principal stops-extend laterally from the bodyof the lever; and the subsidiary stops are at the ends of the inclines on the shells.

When the principal stopsbed against the shells below the ed shoulders reach .the subsidiary stops; greatly increasing the strength of the construction.

The narrower the subsidiary stops are (and they may be very narrow), the wider the jaws of the shells open.

R is the right-hand shell (looking in the direction in which the rope travels); L being the left-hand shell.

A is the ti'unniombolt, A the trunnioncollar and A the nut of one of the adjustment sets claimedin the specification to my United States Letters Patent No. 7284-21.

granted 19 May, 1903.

The pair of principal stop-s D, having becomefirmly bedded against the fronts of the shells R and lg-act instead of the t-run-' nion-peg f as the fulcrum for the lever B.

Pherounded shoulders c then engage with t-he subs1diary' stops [sand is. It will be noticed that the trunnion-peg holes' M and I M are comparatively large; enabling, the shells R and L to rock with the greatest freedom. Such large holes would, however, allow the lever too much play if there were no subsidiary stops. By holdingthehead Z),

the subsidiary stopsprevent the trunnionpeg f moving across the .holes M and M.

- In attaching the clip to the rope,.the'l ong arm of the le'ver B is reckoned from ,the trunnion-peg f to the handle 0; givingfthe maximum leverage. \Vhen-the trunnion-peg f ceases to act as the fulcrum, the long arm is measured from the stops D to the handle 0; diminishing the leverage considerably.

Owing to the decided change in the leverage,

the pressure at the shoulders e is extremely slight. It is. therefore, quite unnecessary for the subsidiary stops to be very prominent.

What I claim as my invention and desire to secure by Letters Patent is 1. A haulage clip comprising a pair'of rocking shells provided with inclines and stops 'at the ends of the inclines, a central adjustable device for connecting the shells, and a lever pivoted to work between the inclines, the lever having lateral-stops on the body and shoulders on the head, the lateral stops bedding against the fronts of the shells and the shouldcrs against the stops at the a pair of rocking shells having compara- 2. A haulage clip comprising a pair of rocking shells provided with lncllnes, a central adjustable device for connecting the shells, and a lever "mounted on a trunnionpeg to Work between the lncllnes, the movement of the lever being limited by a pair of principal stops below and a pair of sub sidiary stops above the trunnion-peg, substantially as described.

3. In a haulage clip, the combination, with tivelylarge trunnion-peg holes and inclines terminated. by subsidiary stops, the shells being connected by an adjustable device, of

a pivoted lever that has lateral stops on the body and shoulders on the head, the lateral stops bedding against the fron e. of the shells and the shoulders against vbsidiary. stops, substantially as set forth.

4. A haulage'clip lever that has lateral stops on the body and shoulders on the head, the lateral stops for bedding against the fronts of a pair ofrocking shells and the shoulders for engaging with subsidiary stops at the ends of inclines on the inner surfaces of the pair of-rocking shells, substantially as represented.
